Specification of Letters Patent.

Patented July 29, i919.

Application filed September 7, 1918. Serial No. 253,008.

enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

The present invention relates, generally, to improvements in mechanical dish-washing machinery; and, the invention has reference, more particularly, to a novel construction of apparatus for use in restaurants,

hotels, homes and in all other places wherein the functions of the machine find utility.

The invention has for its principal object to provide a novel construction of mechanical dish-washing machine providing a maximum of capacity in a very compact space,

by means of which the dishes andtable cutlery may be quickly, easily and safely cleansed with a minimum of physical effort,

and with an appreciable saving of time.

A further object 0f the invention is to provide a novel mechanical dish-washing machine with a plurality of removable dishracks or containers, soarranged and related 3 5 vto the mechanism that the same areeasily passed by the operation of the mechanism successively through the tank containing the hot cleansing water,without any swinglng motion, and in such maintained upright' position. that all danger of the dishes or other contents thereof being thrown out or too violently agitated, tending to loss through breakage, is eliminated, and at the same time the said dishes and other contentsv are presented most effectively to the swirling and cleansing effects of the water.

Other objects of the present invention, not at this time more particularly enumerated, will be clearly understood from the 5o' following detailed description of the' same.

With the various objects of theA present invention in view, the same consists, primarily, in the novel construction of mechanical dish-.washing machine hereinafter set forth; and, furthermore, this invention consists in the novel arrangements and combinations of the various devices and parts, as well as in the details of the construction thereof, all of which will be hereinafter more fully described, and then linally einbodied in the claims appended to said speciication.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a front end elevation of the novel construction of mechanical dish-washing machine, made according to and embodying the principles of my present invention. l

Fig. 2 is a top or plan view of thev same.

Fig. 3 is a detail vertical longitudinal sec-.

tion of the same, taken on line 3-3 in said Fig. 2.

Fig. 4c is a detail transverse section of the same, drawn on an enlarged scale, and taken on line 1 -4 in said Fig. 2.

Fig. 5 is a detail transverse section of one of the removable dish carrying racks or containers, drawn on an enlarged scale, and

arranged to carry plates, saucers and the like; Fig. 6 is a similar view showing the application of mesh containers or baskets to said racks for the support of tablevcutlery, etc.; Fig. 7 is va similar View showing the dish carrying rack as arranged to support cups, drinking glasses, etc.; and Fig. 8 is a detail longitudinal section of the latter arrangement, taken on line 8-8 in said Fig. 7

Similar characters of reference are eniployed in all of the hereinabove described views, to indicate corresponding` parts.

Referring now to the said drawings, the reference character 1 indicatesa suitable tank for holding hot water, said tank 1 being supported by any suitable form ofk standard or frame-work 2, which, however,

is preferably made of angle-iron, so as to provide both strength and durable wearing qualities.

The said tank 1 is preferably open at the top, andjournaled in suit-able bearing brackets 3, attached to its end walls, is a longitudinally disposed shaft 4, which extends through the interior of the said tank, Fixed uponl one of the exteriorlyy projecting ends of said shaft is a crank-handle 5 whereby the machine may be manipulated by hand, although it will be readily understood that any ysuitable means for rotating said shaft byj iiieclijaiiifeal"power may be provided if 'desired'.

'Mounted on said shaft 4, within said tank 1 are a pair of spider-frames 6 having a ality of radiating arms 7, said spiderllfjraines being spaced longitudinally apart so" that they are positioned, one adjacentl to each end wall of said tank.

'loir'. Secured upon an inwardly projecting hub 8 connected with one of said bearing`brack-- ets 3 is a fixed gear 9 which is thus posi-- acent -tov one ofsaid spiderend of each carrying-'frame is a gear 12 for rotating said carrying-frame. Connected n -with each arm 7 `of said spider-frame6, ad-

lao

jacent tothe fixed gear 9, and located upon each said 'arm 7 between said fixed gear 9 and said carrying-frame gear 12, isan outwardly projecting stud 13, upon which is loosely mounted to rotate thereon an idler gear 14, which meshes mutuallywith said V:fixed gear 9 and the adjacentv carryingframe gea-r1.2. j

Each carrying-frame 10, thus rotatably mounted between thel free ends of the arms 7 of said spider-frames`6, is adapted to receive and carry a removable dish-carrying rack or container. Each of said Adish-carrying racks or containers comprisesa pair of end-meme vbers 15 interconnectedby longitudinally'fextending rods 16, which provide support for the articles. arranged within therack or container, and yet, owing to their open or spaced arrangement freely permit cleansing water to sluice between and in cleansing contact with said articles. Each vend-member 15 of said racksor containers is provided adjacent to its upper mar inal edge witha hand-hole 17, in AWhiclit engaged to grasp the racks or containers, for/7 the purpose of lifting the same intov and out 'of operative relation Ato the carrying-frames, and for carrying the racks or containers from place to place. 'Projecting outwardly from the end-members 1'5 of said racks or containers are pairs of studs 18, which. when the racks or containers are inserted within the rectangular inclosures of the carryingframes 10, engage and rest upon the lateral end bars of said carrying-frames, thereby supporting said racks or containers in operative suspended or supported relation to said carrying-frames, as will be understood. The longitudinal side bars of said carryingdependently .knocking against theadjoining plates Adur` the latera e hands may be,J

1,e11,1ve

frames serve to engage the sides of said racks or containers and thus prevent any accidental lateral displacement of the saine from properly supported relation to said carryingz-frames.- l

eferring more particularly to Figo of the drawings, I 'have illustrated therein a erally between the' same, said bars 20 being spaced apart by means of spacing sleeves4 22 `arranged on the rods 19 between the ends o f the barsf20. This spaced arrangement of lateral bars 2O provides a plurality ofcorn. partments in which .plates 23, or the like may be disposed edgewise or upright throughout thefinteriorof the rack or container, in such manner that each plate is insupported' and guarded* against in thel washing operation.

eferring' more particularly to Fig. 6 :of I' the drawings,4 I have'` illustrated therein a preferred interior arrangement of-l rack or container adapted to support or carry silverware, table'cutleryjand the like. vSuch arrangement comprises'the above described 4longitudinal rods V19, lateral bars 20 and spacing sleeves 22, the latter, however, being of asize to 'spacethe lateral bars 20 a little farther apart. 'The/spaced Varrangement of partments in which wire-mesh baskets 21 may be inserted, the latter being so arranged as to support and carry in upright position a plurality of knives, forks, spoons andsimilar'articles 25, which are to be washed, the open mesh of the baskets easily permits the cleansingl water to sluiee therethrough in cleansing engagement with said articles 25. If -so desired` the interior of said baskets may be partitioned transversely with vmesh bars provides a plurality of compartitions 26 to assure the holding of articles 25 inthadesired upright position as shown. Referring more particularly to Figs. 7

and 8 .of the drawings, I have illustrated.

therein a preferred interior arrangement of rack 61""5' container adapted to support or carry cups, drinking glasses and similar ar ticles. Such arrangement comprises -a plurality of longitudinal rods 27 serving as supports, and longitudinal side rods 28 serv-- ing as side guards. ,Extending between a pair of laterally opposite side` rods- 28 are cross guards 29. The said parts 27, 28 and v29, thus arranged, provide compartments at the Ybottom ofthe container or rack adapted to receive and support drinking glasses 30 or similar articles. Additional `longitudinally extending rods 31are proyvided vat each side adjacent to'rtheupper part of. said rack or container for the support of a removable top rack. Said removable top rack comprises en d members 32' having shoulders 33 for engaging said rods 31. Extending longitudinally between 'lower marginal edges of said end members 32 are'fsupporting rods- 34, and above the sametare larranged longitudinal side guard rodsj`35. AExtending between the laterally opposite outer side guard rods 35 are cross guards`36. The said parts 34,35 and 36,

`thus arranged, provide compartments in said top rack adapted to receive and support'cups ,37 or similar articles, which 'may I be locked in place by removable longitudinal vrods 37.

Arranged in connection .with said framework 2, beneath said tank 1, are suitably disposed supporting cradles 38, upon which extra containers or racks mayA be stored. Also connected'with the sides of said framelwork 2, are cradle brackets 39, which alsoserve to hold extra containers or racks. The said cradle brackets 39 are preferably hinged or pivotally connected with said frame-work, 2, so that the same may'. be folded back against the latter when not in use. llVhen said cradle brackets 39 .are -operatively extended or opened out, hooks 40 are lprovided for holding the same in such operative position.

In using the novel dish-washing machine thus constructed, `the racks or containers 'l are loaded with theV soiled dishes, etc., and then vplaced in-thev carrying-frames 10 so as to be suspended between thefree ends of the -arms '7 of the'spider-frame 6. The tank 1.-

being filled with hot water, by turning the crank-handle 5 the shaft 4 is rotated. Since the spider-frames 6 are fast on the shaft 4,

the rotation of said shaft also rotates the spider-frames so that the racks or containers are carried around and successively passed through the hot water. The hot Water sluices through the open racks or containers in and around the contents ofthe latter,

thus washing oli the dirt and grease lfrom the dishes, etc. Since each carrying-frame 10 is in geared relation to the fixed gear 9, it follows, that, as the spider-frames revolve, the idler gears 14 travel around the fixed gear 9, and are thus rotated. The rotationof the idler gears 14 is in turn transmitted to the carrying-frame gears 12, which, being the same size as the .fixed gear 9, make one revolution for each revolution of the shaft 4 and spider-frames 6. The effect.

of this mechanical movement is to always maintain the carrying-frames 10 horizontal while the same are revolved with the spiderframes 6, and consequently the racks or containers supported by said carrying-frames 10 are maintained in upright position at all times, so that there is no swinging oscillawith cleansing effect. The above described,

sun and planet arrangement of gearing for thus controlling and holding the containers or racks upright at all times while being revolved with the spider-frames 6, also makes for an exceedingly compact arrangement, permitting the spacing of the containers or racks closely together, and thus permitting a saving of'biilk as to the com.- plete machine,`and economizing the amount of water necessary for efficient operation. A further advantage of the arrangement is the ease with which it may b e operated, the-racks or containers nicely balancing one another, and since their movements are synchronous with'each other, undue vibration contents is quite eliminated.

The racks or containers, as arranged with the novel carrying-frames, are removable, with ease and speed,'there beingno fastening, locks or catches necessary to be manually operated. The racks or containers are interchangeable so that extra racks or conor jars, tending to accidental injury of their tainers for various sized dishes may be avail-1' 95 sfices and partslas herein set forth, nor'do I confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawings..
